Just recently purchased a 1668 loco. I noticed it only had a number board on one side. There are no slots on the other side for a number board. Is there a reason for this?
I know when I was looking for a 1668 I saw some of these on ebay, but they were always accompanied with WOW !!!!, LOOK, FACTORY ERROR!!!!!. It appears it is much to common to be that significant, but I was just wondering if there was a reason?
Thanks
